Ticketmaster will call for cervantino

You could check at the central ticket office, located to the left of Teatro Juarez (on the walkway to the funicular), in front of the Jardin Union. Or call them, (473) 688-0656/688-0650. I've been to many shows at the Alhondiga with the $90 pesos general admission ticket (you'll need to enter behind the stage, not at the top) but I've never seen a pick-up ticket office there.
